Extended Data Fig. 2: Association of the temperature niche minimum with drier climates.

a. The temperature niche has relatively low population density between 19 °C and 24 °C (blue vertical band). Data for 1980 presented as mean values with the shaded regions corresponding to 5-95th percentiles. b. Frequency distribution of mean annual precipitation (MAP) in the 19-24 °C MAT regions. c. Map of mean annual precipitation with the 19-24 °C MAT regions overlaid (cross hatching) showing they include large areas of deserts.
